Dirichlet spaces with superharmonic weights and de Branges-Rovnyak spaces
Omar El-Fallah, Karim Kellay, Hubert Klaja +2
We consider Dirichlet spaces with superharmonic weights. This class contains both the harmonic weights and the power weights. Our main result is a characterization of the Dirichlet…

Constructive approximation in de Branges-Rovnyak spaces
O. El-Fallah, E. Fricain, K. Kellay +2
In most classical holomorphic function spaces on the unit disk, a function can be approximated in the norm of the space by its dilates $f\_r(z):=f(rz)~(r \textless{} 1)$. We sh…
